so i am writing a code that converts text to speech and save it as output.mp3 and as i enter next text it shows this error

with metadata, open(audio_fname, "wb") as audio:
                   ~~~~^^^^^^^^^^^^^^^^^^^
PermissionError: [Errno 13] Permission denied: 'output.mp3'

so i tried to first play the audio first and wait for 5 sec and then delete but still i am getting error.

ah the folder structureis like this

 main
     text.py
     converter.py
output.mp3

well the audio is being played but after the audio stops and when the code tries to delete it it shows that error

full code

class Speak:
    def __init__(self, text):
        self.text = str(text)

    async def text_to_speech(self, voice='en-US-JennyNeural'):
        # Initialize Edge TTS engine
        communicate = edge_tts.Communicate(self.text, voice)

        # Save the speech as an MP3 file
        await communicate.save("output.mp3")
        
        # Play the MP3 file in a separate thread to avoid blocking
        def play_music():
            pygame.mixer.music.load("output.mp3")
            pygame.mixer.music.play()

            while pygame.mixer.music.get_busy():
                pygame.time.Clock().tick(10)

            try:
                os.remove("output.mp3")
                print("File 'output' deleted successfully.")
            except Exception as e:
                print(f"Error deleting file: {e}")
        
        # Start the playing music in a separate thread
        music_thread = threading.Thread(target=play_music)
        music_thread.start()


# Function to start the voice initiation
async def initiation_voice(text):
    text_instance = Speak(text=text)
    await text_instance.text_to_speech()
